Of course New Leaf has a lot more to offer compared to the DS title and the community seems to be still active here and there. However, If you don't have a problem with missing online features as well as the graphics, then I would say go for Wild World, as it does have a different atmosphere. NL is imo quite similar to NH, while WW offers an experience of the early Animal Crossing area. Besides, the soundtrack is nice and the villager personalities were more sassy/spicy (especially the crankies and snooties), it also has unique events that didn't came back in the newer titles.
